Abstract
A pulmonary valve for use with fitness level respiratory testing equipment, having a tubular silicone rubber body member. Formed at one end of this member is a mouth seal which is subsequently inserted into a subjects mouth. In the superior surface of the tubular body member is found the inhalation ports, these ports allow for air passage during inhalation. Within the tubular body member is housed two valve membranes, one for inhalation and one for exhalation. During inhalation, the inhalation membrane opens, creating an airflow passage-way directly to a subjects's mouth cavity. During exhalation the inhalation membrane closes shut and the exhalation membrane opens thus creating a second and separate airflow passage-way, at the end of exhalation the exhalation membrane closes shut, thus completing one respiration cycle. Because of the unique membrane design there is found no equipment dead space. The pulmonary valve may be equipped with an auxiliary oxygen tank adaptor sleeve which is fitted to the outside of the tubular body member. This adaptor sleeve will accept a hose connecting at one end and creates a gas airflow passage-way to the inhalation ports found in the superior surface of the tubular body member.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
